Provides means to reset all or selectable passwords (roles, users) and/or to delete (the related) sessions, to define a role-based password expiry, to renew your security KEYs & SALTs and to define & monitor your required password complexity/strength. 
Upon password reset, the related users will be informed by eMail. The eMail text can be edited easily through this plugin. 
When the password expiry function is set, users with the related roles will be required to renew their password upon login, once expired. 
When a certain password strength/complexity has been set, the password strength will be monitored and related hints will be displayed accordingly. 
This plugin is self explanatory and can be accessed through the users menu.

Inspired by: andymoyle (Plugin “Emergency password reset V6.1” providing this as a kind of ‘brute force’ functionality) 
Inspired by: Miller Media (Plugin “Expire User Passwords”, providing some basic ideas of functionality but in conflict with the plugin ‘Theme My Login’)

By using Salt Shaker plugin, you’ll be able to harden your WordPress security. It allows you to change the salt keys either manually or automatically.
Try it out on a <a href="https://demo.tastewp.com/salt-shaker" rel="nofollow ugc">free dummy site</a>.
Why Use SALT Keys in WordPress?
When you log in to WordPress, you have the option to remain logged in long-term. To achieve this, WordPress stores your login data in cookies instead of in a PHP session. Malicious individuals can hijack your cookies through various means, leaving your website vulnerable.
To make it harder for attackers to use cookie data, you can take advantage of SALT keys. WordPress SALT keys encrypt your password, making it harder to guess. What’s more, it’s next to impossible for hackers to simply ‘unscramble’ the result in order to get at the original password.

If I have time later, I'll see if I can add the code to add missing salts.
